Marcus Green knows the stress and anger of a customer-service nightmare.

The repetitive phone calls to a string of service agents, each telling him something different.

Letters demanding a resolution that never comes.

He also knows what it’s like when what’s at stake is his most important possession: his home.

“They said, ‘Oh, yeah, we’re gonna get this house.’ I said, ‘You’re going to get this house?’ They said, ‘Yeah.’ I said, ‘Well, is there anything I can do? Is there anyone I can talk to?’ They say, ‘No,’” Green said.

Green sued his mortgage lender, Chase Home Finance, after the bank foreclosed on his New Orleans East home in 2011. Chase tried to take the house shortly after Green rebuilt it using flood insurance proceeds from Hurricane Katrina, and Green’s attorney, Marc Michaud, argues in court filings that Chase committed fraud to justify foreclosing on him.
